CAR-TRUCK.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed July 3, 1913. Serial No. 777,190.

To all whom it ma concern:

Be it known tiat I, CLAUS J. WERNER CLASEN, a citizen of the United States of America, and resident of Davenport, Scott county, Iowa, have invented a certain new and useful Improvement in Car-Trucks, of which the following is a specification.

My invention relates to improvements in car trucks and has special reference to that type generally known as rigid trucks in which the two side frames are securely tied by a transom, but my improved truck has this characteristic difference, instead of the ends of the transom being permanently riveted to the side frames in the usual manner, I yieldingly support the ends of the transom in the side frames and removably secure them thereto in a manner to preserve any and all advantages claimed for the rigid inflexibly riveted truck.

The principal object of my invention is to greatly increase the resiliency or cushioning power of the truck over that of the present day practice, with special reference to freight car and locomotive tender trucks.

Another object is to greatly increase the carrying capacity .Without materially increasing the size of the component parts; and another object is to provide a structure of the character in which the entire truck is assembled and maintained in operative position in a most substantial manner without the use of a bolt or rivet, thus making assembling or dismantling possible any time or any place and without the use of special tools or appliances.

These and other objects which will more fully hereinafter appear I attainby the structure and mechanism illustrated in the accompanying drawings in which Figure I is a top plan view of my improved -truck; Fig. II is a side elevation, partly in section, taken on line A. B. C. D. of Fig. I. Fig. III is an elevation, partly in section taken on line B. C. E. F. of Fig. I. Fig. IV is a vertical cross section taken on line G. H. of Fig. III.

Similar reference characters refer to' similar parts throughout the several views.

The side frames 1. 1. provided with upper and lower arch bars, integral journal boxes, an opening mediate the ends and spring seats each side of and mediate the central opening and the journal boxes,

forms the subject matter of anapplication filed by me July 3rd, 1913, Serial No. 777,192. Instead of rigidly securing the ends of the transom 2, which is of box-like form with an open top except at its ends, to the side frames by riveting same thereto, I pass the ends through the rectangular opening 1 usually employed to receive the ends of the bolster, and suspend same in said openlng by the transom carriers 3 3, which 1n turn are supported at their ends by the trunnions 4 4* extending laterally from the spring caps 5 5, and pass through slots 3 formed in the ends of the transoms. These slots are of a size to closely fit the carriers 3 3 and are located a distance apart to bring one on each side of the side frame and in close proximity thereto, so that when the carriers 3 3 are in place they closely embrace the side frame, fore and aft and effectively lock the transom against longitudinal movement with respect thereto, but as the height of the opening in the side frame is greater than that of the end of the transom, it is,free to move vertigally with respect to the side frame to an extent as governed by the, compressibility of the springs. The springs 6-6 can be much longer and heavier and consequently of greater carrying capacity than the springs employed 1 in the ordinary freight car truck on account of being located at points distant from the center of the side frame and out from under the bolster. Transferring the load from the center of the side frame, where it is usually carried. to points nearer the axles, a side frame of the same size is capable of successfully carrying a much heavier load. My improved truck is similar in character to that class of trucks in which the truck bolster does not extend into or through the side frames and have its movements controlled by the vertical edgesv of said opening. The truck bolster 7 equipped with the usual side bearings 8 8 and center plate 9 is foreshortened and nested within the boxlike transom 2. The ends 10 of the bolster rest on the elliptical springs 11-11 which are carried on the seats 12-12 formed in the floor of the transom 2. The ends of these springs extend laterally through openings 13-13 in the transom. The bolster the transom, in turn, being cushioned in the side frames an unusual degree of resiliency is obtained.

What I claim as new is:

1. In a car truck, the combination with side frames each having an opening mediate the ends thereof; a transom the ends of which extend through said openings; springs seated in said side frame on each side of said opening; and carriers supported by said springs engaging the ends of said transom.

2. In a car truck, the combination with side frames, a bolster disposed between and independent of said side frames; and means yieldingly attached to said side frames adapted to lock the said side framesin 0perative position.

3. In a car truck, the combination with side frames each having an opening mediate their ends; a transom extending through said openings and yieldingly supported by the side frames at points distant from said opening.

4. In a car truck, the combination with side .frames each having an opening mediate the ends thereof; a transom, the ends of which extend through said openings and are yieldingly supported by the side frames at points distant from said openings; and a bolster supported by said transom.- V 5. In a car truck, the combination with side frames each having a transom opening therein; spring seats in said side frame each side of said opening; springs on said spring seats; a transom the ends of which extend through said openings; pairs of carriers supported by said springs and engaging the ends of said transom fore and aftthe side frames; and a bolster supported by said transom.

6.- In a car truck, the combination with side frames each'having a transom opening therein; a transom the ends of whichextend through said. openings and yieldingly supported by said side frames; spring seats in said 'transoms"; springs on said seats and a bolster supported by said springs.

7. In a car truck, 'the'combination with side frames each having a transom opening therein; a transom, the ends of which pass through and beyond said openings; lateral slots throughthe ends of said transom fore and aft the side frames and adjacent thereto; carriers passing through said slots adapted to suspend said transom in said openings free of the side frames; and a bolster supported by said transom.

8. Ina car truck, the combination with side frames each having journal boxes at the ends thereof, a transom opening mediate the said journal boxes; load carrying springs applied to the side frames at each side of said opening; transom-supporting and guidingbars engaging the transom and resting on. said load carrying springs; spring seats and springs in said transom; a bolster supported by said transom springs; said supporting bars in conjunction with said transom adapted to lock said side frames in operative relation.

9. In a car truck, the combination with side frames each having journal boxes at their ends, a transom opening mediate said journal boxes; a pair .of load carrying springs on each side of said opening arranged longitudinally of the side frames in the plane of the webs thereof; spring caps. I
